I am getting ready to bite the bullet and purchase a SR EPS system and I have yet to find any pictures of the under saddle mounting option. Yeah, I know about the wires and what not, but it does not appear that anyone has posted pictures of the power unit mounted at the saddle.

Any of you know?

Curious about this too. Or just anywhere besides at the bottle cages.

Supposedly an under bottom bracket mount as well, using the same mounting kit (not dedicated mounting position as some frames have). Have only seen photos of the brackets, etc, but no photos of it in use...
Also wonder if they mounting options are compatible with Athena EPS as well as Record and SR EPS

Here's to hoping Fairwheel hack EPS and make a reasonable sized brain and battery pack versus what's there now... Will it even fit under most saddles?

The reason I haven't bought one yet is down to it looking like Campy just gave up on developing.

I actually think it was overdeveloped. They were too afraid of the weather out there.

Is it actually any bigger than the Shimano one though? I haven't seen a side by side comparison.

They made it to work even if the bike is underwater (very useful feature :lol: ).

I tried one Sunday, it's just perfect ...

the battery is not too big, it looks ok on the seat tube.

If parking a Fiat 500 on your top tube looks OK :lol: .


The campy unit is bigger than the Shimano but I dont like the Shimano set up either (TOTALLY A PERSONAL THING ON MY PART for both units). I wouldnt build a bike with either one without getting rid of the exterior electronics other than the actual mechs. I think both groups should have done a bit more to find their way inside frames.

i've installed eps on a specialized venge, it installed pretty neatly, drilled one hole in the SP and that was it. if you get the correct cable kits there is plenty length for any frame. they make two mounting kits, i mounted the one designed for seatposts on a metal plate and simply attached this to the saddle rails.

I see two wires along the outside in that pic. Where did you put the wire insert point? I almost got EPS but decided to wait for the battery to get smaller or hacked. We will see about that but in the meantime that under saddle mount has a lot of promise.
I miss the Jerk because your stem is still too short.
Your saddle is probably too high as well.
Oh, and your cleats too far forward.

drilled a hole in LHS of the venge sp and the wires went in there.
